Built to handle intense low-temperature applications—such as industrial blast freezers, quick-freezing tunnels, and low-temp distribution hubs—the 06TTR266 refrigeration screw compressor delivers massive low-temperature capacity. Powered by a heavy-duty 120 HP motor, it provides a displacement of 446 m³/h (266 CFM) at 60Hz and 369 m³/h (221 CFM) at 50Hz.
Specifically engineered for low-evaporating operations using R404A, R507, or R22, its integrated 1-3/8 in. economizer subcooling port maximizes liquid subcooling prior to the expansion valve. This design significantly elevates cooling output and COP during high compression ratio cycles without overloading the motor driver.
To maintain consistent evaporating pressures during rapid pull-down or changing batch loads, the 06TTR266 uses a high-response dual-solenoid capacity modulation system. Offering continuous, stepless unloading from 25% to 100%, the compressor adapts fluid flow to instantaneous thermal conditions.
Internal volume ratio (Vi) tuning prevents partial-load over-compression penalties, reducing electrical consumption during holding phases and stabilizing low-temperature storage climates.
Weighing 613 kg, this semi-hermetic compressor features a heavy-duty structural casing that dampens vibration in demanding mechanical rooms. Using an internal pressure-differential lubrication scheme, it operates reliably without external oil pumps.

For over two decades, Ruifujie has stood as a trusted global supply partner in commercial and industrial refrigeration. We deliver high-performance screw, semi-hermetic reciprocating, scroll, and rotary compressors alongside turnkey cold storage and quick-freezing equipment.
Through robust engineering support, strict quality verification, and flexible OEM/ODM manufacturing, Ruifujie serves engineering contractors and equipment wholesalers across North America, Europe, the Middle East, and Southeast Asia. We prioritize long-term B2B partnerships by pairing top-tier mechanical reliability with direct factory pricing.
Operating at low evaporating temperatures creates steep compression ratios. The 06TTR266 combines 446 m³/h displacement with a dedicated 1-3/8 in. economizer circuit, boosting subcooling and volumetric efficiency so the system can achieve deep freezing temperatures rapidly.
In low-temp freezing systems, suction gas density is low. The 4-1/8 in. suction connection prevents fluid throttling and reduces pressure drop at the compressor inlet, allowing maximum gas mass flow into the twin screw rotors.
Y-Δ starting is recommended. On a 460V 60Hz line, Star-Delta configuration drops the starting inrush current from 930A down to 298A, protecting factory transformers and preventing voltage drops.
No. The compressor relies on internal pressure-differential oil circulation. Lubricant flows naturally through internal channels to protect the SKF/NSK bearings, reducing system mechanical complexity.
Every compressor is pressure-tested, vacuum-dried, charged with protective dry nitrogen, sealed in moisture-proof packaging, and secured within a heavy-duty plywood export crate to withstand sea transit.
